I am very suprised that your Muzzy's shoot the same as an expandable.
That means your bow is not tuned exactly right. Since I learned how to tune a bow about 15yrs ago, I've never had ANY fixed BH flight problems, they fly right with my FP's. Muzzy's fly excellent for sure.
It wouldn't hurt to bring 2 different types with you - as long asyou know for sure they both hit where you aim. I personally only have 1 in my quiver.
